Can depression change the way you look?

Ive been depressed for three years and finally decided to get help. but one of the things I had the biggest problem with was that I looked like crap all the time it seemed like over the years my face and body were drooping down. so I thought that my pills helping me sleep (because before i had severe insomnia) and gaining weight from eating better would make a big difference in my appearence but it's been three months and I still look at myself in the mirror and am like uugghhh i look like ****. plus during the day I still feel exhausted/tired and have body ache. please help
